referred by Mr R. F. Tomzs* to the following :—Thecosmilia 
gregaria, Isastrea tenuistriata, Thammastrea mettensis, T. Wrightia 
(new species,) Microsolina sp., Microsolina regularis, Montlivaltia 
sp., &c. This is the same bed as that on the hill on the 
opposite side of the valley, at Worgan’s quarry. At a pointa 
few yards lower down the hill the lower coral-bed of the 
“Inferior Oolite” presents itself; it is largely quarried for 
road-stone, and at this point is about ten feet thick. Here 
Dr Wricut, at the request of those present, gave an instructive 
address on the formation of coral reefs, and deduced from tlie 
entire change in the forms of life of the builders of the three 
known coral-beds of the “Inferior Oolite” that an enormous 
duration of time must have elapsed between the deposition of 
each of these beds, seeing that the vast reef of Florida, miles 
of which now form dry land, has been shown by Agassiz to 
have required at least 70,000 years for its formation, while the 
same industrious little builders by which it was constructed are 
busy at this day, continuing the work in the adjoining seas. 
Mr R. F. Tomszs, in a Paper lately read before the Geological 
Society, adopts in general Dr Wricut’s views as to the strate- 
graphical position of the coralligenous deposits in the “Inferior 
Oolite” of Gloucestershire, and gives a tabular statement of 
the distribution of species in the several coral-beds, pointing 
out that each of these has its own species, which do not pass 
much from one to the other. 
At the invitation of Mr Lucy the party adjourned to the 
residence of his son, where tea was offered, and gratefully 
accepted. After a hasty look (it was all the time allowed) at 
the very beautiful garden, with its wealth of interesting plants, 
gathered by a former proprietor from all parts of the European 
Continent, and here to be seen blooming in rare perfection, the 
carriages were again in motion for Stroud, where, at the Imperial 
Hotel, the party found an excellent dinner prepared for them. 
After dinner Dr Wricut drew attention to the fact that,
